If you are still seeing issues with those already deleted.. it's probably because of something on the embedded. (either your class.. or our class that we delivered you). If you're still seeing those issues I will need some code from you starting this data and replicating that other issue.

Ok so ive got some bad news... this morning, the queues stopped delivering again. I dont have access to the data files right now, but ill analyze them later (and maybe send them to you if you're interested)

Ill try to start hornetq as a standalone server (and not embedded), but i dont think that is the problem - i am literally just starting the EmbeddedJMS class but maybe some other service needs to be configured. I have 1 AddressSettings, 2 Acceptors (one for the in-vm and the other a netty), a discovery and a broadcast services for cluster discovery, two connection configuration (again, an in-vm one and a netty one) and finally the queues and a topic.
